We stock all of the fasteners you need to build your truck or caravan shell.


Lavender Composites supplies a range of quality fasteners including Bulb-Tite aluminium rivets, Panelock bolts, Wing Pias countersunk wing screws and Monolock bushes.

These fasteners are all designed for applications requiring the tensile load to be spread over a large area, such as when fastening plastics, fibreglass and other composite materials.


  • Strong
  • High quality
  • Load spreading
  • Rivets and Panelock bolts fitted with neoprene washers to ensure water-tight seal


Bulb-Tite rivet – For fixing brackets or sections to one skin of a composite panel. During installation, the rivet body folds into three separate legs, creating a large load-bearing area and minimising the possibility of damage to the panel skin material. These rivets are supplied with a neoprene washer under the head to provide a weather-tight seal.

Panelock bolt and nut – Structural bolt for fixing composite panels to aluminium structural extrusions and steel sections. Fitted with neoprene washer to provide a weather-tight seal.

Countersunk wing screw – Used to fix Holypan panels to metallic structures and provide a flush finish on the panel face after installation. Suits 12mm to 30mm panels.

Monolock bush – Used to fix 30mm panel to a structural frame (typically floor). The panel upper skin and core is removed and the bush fills the void providing a flush fixing.
